scribed above) ; the upper of the two mesepimeral spots is pronouncedly 

 metallic-green and longer, its upper end reaching to the humeral suture, 

 although not quite attaining the antealar sinus (connected with the 

 lower mesepimeral spot in the oldest male from Cuyaba); metallic- 

 green of the abdominal dorsum reaching back to segment 7 so far as the 

 abdomen is present, 8 also showing some pruinosity, transverse basal 

 ring present also on 7 ; 8-10 postnodals on the front wing, 9-10 on 

 the hind; abdomen 27 mm. ; hind wing 17-18 mm.

The supposed types of Hagen are before me, although the abdomen 

 of the male measures 36 instead of 34 mm. The " raie humerale 

 orangee " is strictly mesepimeral and in the female, as in the male, is 

 " suivie d'un espace brun jusqu'a la premiere suture laterale." The 

 pectus may have been bluish or yellowish ; there is an elongated iso- 

 lated metepimeral black spot on the anterior end of the latero-ventral 

 carina, and a smaller blackish metasternal spot farther posterior and 

 close to the carina ; mid-ventral groove black. 



A female from Chapada may belong to this species ; the differences 

 from the type female which it shows are at least too slight to refer it 

 to another species in the absence of any male with which it might be 

 conspecific. A comparison of the type female follows, the parentheses 

 enclosing statements concerning the type: abdomen 30 (32) mm. ; 

 hind wing 22 (23) mm. ; costal edge of stigma front wing 1.3 (1.5) 

 mm.; width of head 3.4 (3.7) mm.; maximum width of thorax 2.7 

 (3.0) mm.; sides of the thorax pale bluish (yellow); dorsum of ab- 

 dominal segments 2-6 dark brown without metallic-green reflection 

 (darker, with a slight metallic-green reflection);- 10-11 (12-13) 

 postnodals on the front wings, 10 (12) on the hind. 



In both females the blackish mesepisternal stripe — the " raie noire
